CSV in Ruby 1.8.7 and 1.9.2

Hi all,

I am trying to generate a CSV with the code bellow:

csv_string = CSV.generate(:col_sep => “\t”) do |csv|
csv << [“row”, “of”, “CSV”, “data”]
csv << [“test”, “ao”]
end

But when I try with Ruby 1.8.7 I get the follow error:

ruby-1.8.7-p249/lib/ruby/1.8/csv.rb:326:in `initialize’: can’t convert
Hash into String (TypeError)

And if I try to call the generate methos without arguments, I get a
error too

If I try with 1.9.2 I get the error:

gerar.rb:35: invalid multibyte char (US-ASCII)
gerar.rb:35: invalid multibyte char (US-ASCII)
gerar.rb:35: syntax error, unexpected $end, expecting ‘]’

How to fix this?

That’s because Ruby 1.8.7 has a different CSV library. You’ll need to
use FasterCSV there to get the same interface. Change your require to
something like:

if RUBY_VERSION < “1.9”
require “rubygems”
require “faster_csv”
CSV = FCSV
else
require “csv”
end

If I try with 1.9.2 I get the error:

gerar.rb:35: invalid multibyte char (US-ASCII)
gerar.rb:35: invalid multibyte char (US-ASCII)
gerar.rb:35: syntax error, unexpected $end, expecting ‘]’

This is a non-CSV related complaint about your code. On line 35 of the
gerar.rb file you have used a non-ASCII character. To do this in Ruby
1.9, you must specify the encoding of your file. If it’s UTF-8, making
this the first line of the file should fix it:

encoding: UTF-8

Hope that helps.
